首先说一下扫雷规则。
1.数字是几就表示此数字位置邻接的八个方向有几个地雷
2.鼠标右键单击一次标记此位置为地雷（插上一个小旗），再单击一次标记为？
3.鼠标左键单击某位置
如果这个位置上的数字为1-8 即显示
如果为数字为0（即空白） 自动延伸八个方向直到遇见数字（1-8）为止
如果为地雷，游戏失败
4.当地图上的所有数字都点击完毕 游戏胜利
首先是MineClient类，初始化地雷，有刷新线程，画图等等

解释两个变量。、
what表示当前地雷（不一定是地雷）所画的内容
hide表示当前地雷（不一定是地雷）真实的内容
解释两个方法
public Rectangle getRec() {
return new Rectangle(x, y, w, h);
}
返回当前地雷的矩形，具体作用我会在MyMouseListener类里面说

MyMouseListener类（自定义的鼠标事件）
最难的都在这里面了
1.开始玩游戏的时候要保证第一下点击的不是地雷
2.点击到数字0（空白）时自动延伸
解决：
在解决问题之前 我们要首先知道鼠标点击的是哪个地雷
<span style="white-space:pre"> </span>int x = e.getX();
int y = e.getY();
Rectangle rec = new Rectangle(x, y, 1, 1);
for (Bomb bomb : bombList) {
if(rec.intersects(bomb.getRec())){
//表示鼠标矩形和地雷矩形相交
}
}
解释一下，我们可以通过getx() ,gety()方法获得当前鼠标的坐标 然后把鼠标的宽和高认为1 new一个矩形对象
然后通过API提供的intersects方法判断两个矩形是否相交，也就是鼠标点击的地雷位置
1.为了保证第一次点击时点击不到地雷，我们在mousePressed(MouseEvent e)方法中初始化地图，把当前鼠标
点击的位置设置为地雷，当随机初始完地雷后再把当前位置恢复默认
2.这个应该是最难的了吧。当然 如果你学过算法中的搜索 那么久太简单了
DFS和BFS都行。从当前位置出发，向它的八个方向进行深搜 直到遇到数字结束当前递归
感觉这两个比较难 其它的有疑问可以留言 一起解决~~
